Antagonism bw. EB and magnetostriction: Normalized magnetization curves (black) and magnetostriction curves (red) of Fe₅₀Co₅₀ multilayers deposited on cantilevers. a,b, The pinning direction is induced either parallel (a) or perpendicular (b) to the longitudinal cantilever axis. Whereas the exchange bias shows a maximum value when measured parallel to the pinning direction, the magnetostrictive response almost vanishes. In the case of the measurement perpendicular to the pinning direction, the projection of the exchange bias vanishes; however, the magnetostrictive response is maximal.
